(tripleo heat templates) Not configuring neutron mechanism drivers in any puppet based deploys

[Marios Andreou]

Neutron Mechanism Drivers for the overcloud aren't configured as whilst we have the tripleo heat templates param and also pass the value in hiera data, we do not consume any passed value. Our default (tripleo heat templates say 'openvswitch' for the default, description of what this config is at [2]) but the deployment gets the puppet-module default like

./plugin.ini:20:mechanism_drivers =openvswitch,linuxbridge
./plugins/ml2/ml2_conf.ini:20:mechanism_drivers =openvswitch,linuxbridge

 Even though we end up with correct behaviour (since afaik we've only ever used openvswitch for ml2 here) I think the bug is the expectation that the config item is configurable via the tripleo heat template param, which it is not in reality (tripleo image element deploys do consume and set this in the pass though data)

    Consume the NeutronMechanismDrivers from the hiera data

    This is passed from the heat templates as hiera data (defaulting
    to 'openvswitch') but never effected, meaning we get the puppet
    module default.
